Step 1:
Preheat the oven to 450 degrees. Place the pizza crust on a baking sheet.

Step 2:
Cut the shrimp in half lengthwise. In a frying pan, heat the oil with the garlic over medium heat. As soon as the garlic sizzles, add the shrimp and saute just until they turn pink, about 1 minutes. Stir in the oregano and season to taste with salt and white pepper. Remove from the heat and sprinkle in the lemon juice.

Step 3:
Arrange the shrimp on top of the pizza crust, spooning the juices from the pan evenly over the crust up to 1/2 inch from its edges. Scatter the tomato on top. Crumble the feta over the pizza and sprinkle evenly with mozzarella.

Step 4:
Bake the pizza until the cheese is melted, about 10 minutes. Remove from the oven, transfer to a cutting board, and cut into slices.
